There you can also find the necessary information how to connect the module.<\/p>\n<ul>\n<li><a href=\"https:\/\/github.com\/pschatzmann\/arduino-audio-tools\">arduino-audio-tools<\/a><\/li>\n<li><a href=\"https:\/\/github.com\/pschatzmann\/arduino-vs1053\">arduino-vs1053<\/a><\/li>\n<\/ul>\n<h3>Encoded Audio Output Example<\/h3>\n<p>In the <strong>audio-tools<\/strong> you can find a <a href=\"https:\/\/github.com\/pschatzmann\/arduino-audio-tools\/tree\/main\/examples\/examples-vs1053\">couple of examples<\/a> that demonstrate how to use the  module: In a nutshell you can just use it <strong>like any other audio audio sink<\/strong> with the following main difference: You can directly send aac, mp3, midi and wav files  because the module can decode these format itself.<\/p>\n<p>Just to show how easy it is, here is the code for a <strong>streaming web music player<\/strong> on an ESP32:<\/p>\n<pre><code>#include \"AudioTools.h\"\n#include \"AudioLibs\/VS1053Stream.h\"\n\nURLStream url(\"ssid\",\"password\");  \/\/ or replace with ICYStream to get metadata\nVS1053Stream vs1053; \/\/ final output\nStreamCopy copier(vs1053, url); \/\/ copy url to decoder\n\nvoid setup(){\n  Serial.begin(115200);\n  AudioLogger::instance().begin(Serial, AudioLogger::Info);  \n\n  \/\/ setup vs1053\n  auto cfg = vs1053.defaultConfig();\n  cfg.is_encoded_data = true; \/\/ vs1053 is accepting encoded data\n  \/\/ Use your custom pins or define in AudioCodnfig.h\n  \/\/cfg.cs_pin = VS1053_CS; \n  \/\/cfg.dcs_pin = VS1053_DCS;\n  \/\/cfg.dreq_pin = VS1053_DREQ;\n  \/\/cfg.reset_pin = VS1053_RESET;\n  vs1053.begin(cfg);\n\n  \/\/ mp3 radio\n  url.begin(\"http:\/\/stream.srg-ssr.ch\/m\/rsj\/mp3_128\",\"audio\/mp3\");\n\n}\n\nvoid loop(){\n  copier.copy();\n}\n<\/code><\/pre>\n<h3>File Formats<\/h3>\n<p>The module supports the <strong>decoding<\/strong> of the following <strong>audio file formats<\/strong>:<\/p>\n<ul>\n<li>Ogg Vorbis<\/li>\n<li>AAC<\/li>\n<li>WMA<\/li>\n<li>MP3<\/li>\n<li>MP1 &amp; MP2<\/li>\n<li>ADPCM<\/li>\n<li>PCM<\/li>\n<li>WAV<\/li>\n<li>FLAC <\/li>\n<li>Midi<\/li>\n<\/ul>\n<h4>Midi Files and Conversion to Format 0<\/h4>\n<p>General MIDI and <strong>SP-MIDI format 0 files<\/strong> are played. <strong>Format 1 and 2 files must be converted to format 0 by the user<\/strong>!<\/p>\n<p>I was looking for a tool to do this, but did not find anything useful. Finally I used the following Python Code to convert the format 1 files to format 0 with the help of the <strong>&#8216;mido&#8217; library<\/strong>:<\/p>\n<pre><code>import mido\nfrom mido import MidiFile,MidiTrack\n\nmid1 = MidiFile('file-1.midi')\nmid0 = MidiFile()\ntrack0 = MidiTrack(mido.merge_tracks(mid1.tracks))\nmid0.tracks.append(track0)\nmid0.type = 0\nmid0.save('file-0.midi')\n<\/code><\/pre>\n<p>Format 1 files have multiple tracks whereas format 0 files have only 1 single track. The code simply merges the tracks into 1.<\/p>\n<h2>Output of PCM Audio Data<\/h2>\n<p>Most of the functionality of the library is using <strong>PCM data<\/strong>. I wanted to be able to use this functionality as well, so all I needed to do was to <strong>automatically convert the PCM stream to the WAV format<\/strong>. Therefore we can use the usual fuctionality w\/o any changes. Here is the example that outputs a sine wave:<\/p>\n<pre><code><br \/>#include \"AudioTools.h\"\n#include \"AudioLibs\/VS1053Stream.h\"\n\nuint16_t sample_rate=44100;\nuint8_t channels = 2;                          \/\/ The stream will have 2 channels \nuint8_t bits_per_sample = 16;                  \/\/ 2 bytes \nSineWaveGenerator&lt;int16_t&gt; sineWave(32000);    \/\/ max amplitude of 32000\nGeneratedSoundStream&lt;int16_t&gt; sound(sineWave); \/\/ Stream generated from sine wave\nVS1053Stream out;                              \/\/ VS1053 output\nStreamCopy copier(out, sound);                 \/\/ copy sound to VS1053\n\n\nvoid setup(){\n  Serial.begin(115200);\n  AudioLogger::instance().begin(Serial, AudioLogger::Warning); \/\/ Info is causing noise  \n\n  \/\/ Setup sine wave\n  sineWave.begin(channels, sample_rate, N_A4);\n\n  \/\/ setup output\n  auto cfg = out.defaultConfig();\n  cfg.sample_rate = sample_rate;\n  cfg.channels = channels;\n  cfg.bits_per_sample = bits_per_sample;\n  \/\/ Use your custom pins or define in AudioCodnfig.h\n  \/\/cfg.cs_pin = VS1053_CS; \n  \/\/cfg.dcs_pin = VS1053_DCS;\n  \/\/cfg.dreq_pin = VS1053_DREQ;\n  \/\/cfg.reset_pin = VS1053_RESET;\n  out.begin(cfg);\n\n}\n\nvoid loop(){\n  copier.copy();\n}\n\n<\/code><\/pre>\n<p>Because <code>cfg.is_encoded_data = false<\/code> is the default setting, we can omit this in the configuration!<\/p>\n<h2>Examples<\/h2>\n<p>Here are a couple of additional examples:<\/p>\n<ul>\n<li><a href=\"https:\/\/github.com\/pschatzmann\/arduino-audio-tools\/tree\/main\/examples\/examples-vs1053\/streams-generator-vs1053\">streams-generator-vs1053<\/a><\/li>\n<li><a href=\"https:\/\/github.com\/pschatzmann\/arduino-audio-tools\/tree\/main\/examples\/examples-vs1053\/streams-memory_midi-vs1053\">streams-memory_midi-vs1053<\/a><\/li>\n<li><a href=\"https:\/\/github.com\/pschatzmann\/arduino-audio-tools\/tree\/main\/examples\/examples-vs1053\/streams-url_mp3-vs1053\">streams-url_mp3-vs1053<\/a><\/li>\n<li><a href=\"https:\/\/github.com\/pschatzmann\/arduino-audio-tools\/tree\/main\/examples\/examples-vs1053\">and more &#8230;<\/a><\/li>\n<\/ul>\n","protected":false},"excerpt":{"rendered":"<p>I added support for the VS1053 breakout boards to my Arduino Audio Tools project.
